title: Nonlinear dynamic behavior of cardiac oscillators.
abstract: By studying a mathematical model of the effects of brief current impulses on the oscillation of cardiac cells, we have simulated the phase transition curves of the oscillators. This has permitted discussions of the interactions of two coupled sinus oscillators and the periodic stimulation of one ventricular oscillator. The results have been compared with findings from the normal electrocardiogram and applied to explain the mechanisms of some arrhythmias.
